ANTIBACKFIRING ATTACHMENT FOR CARBURETERS.

Specification of Letters'Patent.

Patented Mar. 2, 1915.

Application filed June 9, 1913, Serial No. 772,627. Renewed January 22, 1915. Serial No.'3,841.

To all whom may concern:

Be it known that I, JULIUS VON WLADKOW- SKY, a subject of the Emperor of Austria- Hungary, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Antibackfiring Attachment for Carbureters, of which the following is a full, clear, and exact description.

This invention relates to a device designed for use in connection with internal combustion engines for preventing backfiring thereof through the carbureter.

The invention has for its general objects to improve the construction of devices of this character so as to be more reliable and efficient in use, comparatively inexpensive to manufacture and so designed that it can be readily applied as an attachment to carbureters already in use.

Another object of the invention is to provide an anti-backfiring device which by its novel construction has the additional functions of causing a better mixture of fuel and air and reducing fuel consumption.

A further object of the invention is the provision of a screen which is placed in the mixing conduit and has on the engine side thereof a baffling or deflecting device whereby the force of the gas at the time of backfiring is overcome to such an extent that the flame cannot pass through the screen, such baffling device being in the formof vanes which deflect the gas and give the same a rotary movement around the screen.

Another feature of the invention is the use of a bafliing device as a means for centering the attachment in the mixture conduit of the engine, such baflling device being spaced from the body of the screen by a central hollow stem on the latter, which stem holds porous material that is adapted to become saturated with gasolene so that vaporizing of the fuel is greatly facilitated and starting of the engine made easier.

With these objects in view, and others as will appear as the description proceeds, the invention comprises various novel features of construction and arrangement of parts which will be more fully described hereinafter and set forth with particularity in the claims appended hereto.

In the accompanying drawin which illustrate one embodiment of the invention,

and wherein similar reference characters are employed to designate corresponding parts throughout the several views, Figure 1 is a side view of a carbureter and engine manifold with portions broken away to show the anti-backfiring and fuel saving attachment in position; Fig. 2 is a plan view of theattachment; and Fig. 3 is an enlarged sectional view thereof.

Referring to the drawing, A designates an ordinary carbureter which is connected with the manifold B of a gas engine, there being at the point of connection the attachment C which forms the subject matter of the present invention. This attachment comprises an approximately semispherical screen 1 of copper or other Wire netting, there being a reinforcing ring 2 around the periphery thereof, said ring being clamped between the flanges 3 and 4 of the carbureter A and manifold B, and if desired a packing ring 5 may be employed to eflectively seal the joint. The central portion of the screen is shaped into a hollow stem 6 which forms a support for the baflle device 7 that is spaced from the body of the screen by the stem- 6. This bafliing device comprises a plurality of vanes 8 which are given a pitch similar to the vanes or blades of a fan or propeller, and these vanes are of such length that the diameter of the baffling device is practically the same as the diameter of the manifold B in which the bafliing device 7 is positioned, and consequently the bafiiing device serves to centralize the attachment when it is being assembled. Between the manifold and carbureter the hollow stem 6 is filled with cotton 9 or equivalent material and held in place by a piece of gauze 10 which is soldered or otherwise secured within the chamber side of the screen. The hollow side of the screen 1 is presented to the carbureter so as to provide clearance for the throttle 11 in those carbureters where butterfly throttle valves are used, but it is to be understood that the screen 1 is made rounded primarily for the purpose of obstructing the passage of the flame through the screen. In case of a backfire the force of the gas is broken by means of the bafiling no force to; cause the flame to pass through the mesh of the screen. It is well known that a flame of low pressure will not pass through a wire netting, and as the bafiing device 7 greatly reduces the pressure of the backfiring gases the flame does not pass into the carbureter. 'llhe screen 1 and porous materials 9 act to arrest the particles of gasolene that would otherwise be sucked into the manifold and eventually into the engine during the suction strokes of the pistons, and furthermore a better vaporizing action is obtained so that the consumption of fuel isl-reduced and engine troubles also minimiz'ed.

From the foregoing description taken in connection with the'acconipanying drawings, the advantages of the construction and method of operation and of the device shown will be readily-understood by those skilled in the art to which the invention appertains, and while I have described the principle of operation, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the deviceshown is merely illustrative, and that such changes may be made when desired as are within the scope of the appended claims.

Having thus described my invention, ll

memes claim as new and desire to secure by Letters Patent:

1. A. carbureter attachment of the class described comprising a gauze screen, a vaporizer thereon including absorbent material, and a bafiing device also mounted on the screen. p

2. An attachment of the class'described comprising a means connecting the device with the screen and forming a vaporizer.

3. A carbureter attachment of the class described comprising a screen, a hollow central stem thereon, a baiiling device carried by the stem,

4. A carbureter attachment of the class described comprising a screen having a central portion formed into a hollow stem, porous material in the stem, means attached to the screen for holding the said material in the stem, and a bafliing device secured to the extremity of the stem.

In testimony whereof l have signed my name to this specification in the presence of two subscribing witnesses.
